Hybrid tea rose plant named Ruidriko

ABSTRACT

A new variety of hybrid tea rose having light pink flowers with long vase-life and lasting quality produced on a plant suitable for growing under glass.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by me by crossing, as seed parent the variety known as "Korflug" and as pollen parent, the variety known as "Ruimeva". The varietal denomination of this new rose is "Ruidriko".

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive light pink flowers borne on a plant particularly suited for growing under glass to produce cut flowers. "Ruidriko" can be reproduced through propagation by cuttings, budding, grafting and micropropagation. Flowers of the new variety are long lasting on the plant and have long vase-life as cut flowers. Asexual reproduction by budding and grafting and by propagation by cuttings of the new variety as performed in Hazerswoude, Holland, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawings show typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in color illustrations of this character. However, the color representation in the illustration of details of the new variety in FIG. 1 are more accurate and the illustration of cut flowers in FIG. 2 is intended to show the excellent form of the new variety.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is an illustration showing details of the new rose variety, "Ruidriko"; and

FIG. 2 is an illustration of cut flowers of the new variety to illustrate flower form.

DESCRIPTION OF PREFERRED EMBODIMENT

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC) and horticultural terminology in accordance with standard terminology used in UPOV-approved horticultural guidelines. The terminology used in color descriptions herein refers to plate numbers in the aforementioned color chart.

Parentage: Seedling.

Seed patent.--"Korflug".

Pollen parent.--"Ruimeva".

Class: Hybrid tea.

As can be seen in the accompanying illustrations, FIG. 1 shows details of the new variety "Ruidriko". In the illustration there is shown the top of a young shoot 1; examples of foliage as compound three, five and seven leaflet leaves, 2, 3 and 4, respectively, a stem 5; flower buds, 6, after sepals fall and, 7, after petals begin to unfurl; a flower, 8, about one-third to one-half open; and a flower 9, fully open. Also shown are flower stems 10, 11 and 12, with reproductive organs but without petals.

FIG. 2 shows specimens of cut flowers of "Ruidriko" showing the appealing exhibition form of this variety.

The following further horticultural observations were made of specimens grown outdoors in Holland.

As flower opens, color of petal top surface becomes in the range of 56C to 39C-D. Petals at point of attachment are near 2C. Overall tonality from a distance is an attractive creamy light pink.
